PRECAUTIONS


Precaution


NOTE:
If any malfunction occurs in the RE0F10A model transaxle, replace the entire transaxle assembly.





- Before connecting or disconnecting the TCM harness connector, turn ignition switch OFF and disconnect negative battery cable. Because battery voltage is applied to TCM even if ignition switch is turned OFF.





- When connecting or disconnecting pin connectors into or from TCM, take care not to damage pin terminals (bend or break).
When connecting pin connectors make sure that there are not any bends or breaks on TCM pin terminal.





- Before replacing TCM, perform TCM input/output signal inspection and make sure whether TCM functions properly or not. TCM Input/Output Signal Reference Value.





- After performing each TROUBLE DIAGNOSIS, perform "DTC
Confirmation Procedure".
If the repair is completed the DTC should not be displayed in the "DTC Confirmation Procedure".
- Always use the specified brand of CVT fluid. Maintenance.
- Use lint-free paper, not cloth rags, during work.
- After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
- Before proceeding with disassembly, thoroughly clean the outside of the transaxle. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
- Disassembly should be done in a clean work area.
- Place disassembled parts in order for easier and proper assembly.
- All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
- Gaskets, seals and O-rings should be replaced.
- It is very important to perform functional tests whenever they are indicated.
- Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and seals.
- Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
- Clean or replace CVT fluid cooler if excessive foreign material is found in oil pan.
- When the CVT drain plug is removed, only some of the fluid is drained. Old CVT fluid will remain in torque converter and CVT fluid cooling system.
Always follow the procedures under "Changing CVT Fluid" in the Continuously Variable Transmission when changing CVT fluid. Checking CVT Fluid, Changing CVT Fluid.

TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
- External leaks in the hub weld area.
- Converter hub is scored or damaged.
- Converter pilot is broken, damaged or fits poorly into crankshaft.
- Steel particles are found after flushing the cooler and cooler lines.
- Pump is damaged or steel particles are found in the converter.
- Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnosis have been made. (Converter clutch material may be glazed.)
- Converter is contaminated with engine coolant containing antifreeze.
- Internal malfunction of stator roller clutch.
- Heavy clutch debris due to overheating (blue converter).
- Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are worn or damaged -- indicates that lining material came from converter.
The torque converter should not be replaced if:
- The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
- The threads in one or more of the converter bolt holes are damaged.
- CVT malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate lining material in unit and inside the fluid filter.
- Vehicle has been exposed to high mileage (only). The exception may be where the torque converter clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, such as taxi, delivery or police use.
